This presumably has something to do with boot2, which has an important role in the booting sequence. If is ran after being decoded from boot1, which is in turn ran after being decoded from boot0 which is read only. (See the boot2 page).
This accepts the following commands: open, close, read, write, seek, ioctl, ioctlv
IOCTL example:
14 ioctl(0,4,12 return -101)
ioctlv 4,12,14 last only in IOS56+
/dev/boot2 IOS_Ioctlv

/dev/boot2 error codes
Note: POSIX is a standardized system that helps maintain compatibility between many different operating systems. So, each error code shown below has a given POSIX equivalent (not known yet). Other OS's many have different error code numbers, but if their POSIX equivalent is the same, they mean the same thing.
| Error code | POSIX equivalent | Notes |
|---|---|---|
| -101 | ? | This can refer to: Invalid Wrong IN or OUT size, wrong size for a part of the vector, vector alignment problems, non-existant ioctl, or wrong structure. |
| -102 | ? | ? |
| -104 | ? | ? |
| -106 | ? | ? |
| -107 | ? | ? |
| -108 | ? | ? |
